Review on 🔧 Sanding Scraps Delight: Craft Your Projects with Various Shaped Sanding Blocks by Jonathan Brendemuehl

Randomness in size and granularity greatly reduces its usefulness. I didn't find any that were too gross, but there were some that were so good I would never use them. Maybe it's better to buy exactly what you need. I make wooden toys and use them to sand small parts. Especially in holes.
